33 CFR §83.35(c) groups sailing vessels with vessels not under command, vessels restricted in ability to maneuver, vessels engaged in fishing, and vessels towing or pushing, all of which sound one prolonged followed by two short blasts at intervals of not more than 2 minutes. One prolonged followed by three short blasts is the signal for a vessel being towed.
